volume efficiency start -vserver vs1 -volume vol1 -scan-old-data true -b
I am running 8.2.1P1
There was a opton, "-snapshot-blocks true", it should compress locked snapshot. This is how I understood. However, the option did not work, and error message was "invalid argument". I used "-b" option instead, and accepted. according to TR-42369, should it do the same as "-snapshot-blocks true", is that true?
The following command would not work neither, it should work according to TR-3966.
volume efficiency start -vserver vs1 -volume vol1 -scan-old-data true -compression true -dedupe true -shared-blocks true -snapshot-blocks true
I wanted to make sure snapshots will be included in compressing?
The volume "vol1" that I am working on is 1.6TB volume for vmware vcenter, about 1.2TB are logs and yet snapshots, and that's why I wanted to use "-snapshot-blocks true" optioin.
Should it considered to be nornal that neither compression nor dedup did much saving on logs? I only saved 3% by deduping? Any logic explaination here?
Pls stay with me to get it done.
Thank you!
